lib/oe/utils.py: add get_host_compiler_version()
Add helper function to get the host compiler and version. Do not assume compiler is gcc. NOTE: cannot set env to d.getVar("PATH") as that does not contain the session PATH which was set by environment-setup-... which breaks the install-buildtools use-case Signed-off-by: Tim Orling <timothy.t.orling@linux.intel.com>
